My invention relates to window guards for use in connection with sliding sashes, and among other objects, aims to provide an improved collapsible guard for the lower win dow sash having provision to be opened and closed at will as the sash is raised and lowered and also having means either to connect the guard to the inside of the lower sash whereby the guard may be opened and closed with it or to lock the guard in closed position to the inside of the upper sash. Further, the invention contemplates means whereby the guard may be collapsed so as to occupy a relatively small space below the lower rail of the upper sash where it is relatively inconspicnous. I

Apparatus embodying features of my invention is illustrated in the accompanying drawing, wherein:

Fig. 1 is a view in front elevation of the lower part of a window having my improved guard means applied thereto and showing the guard in closed position;

Fig. 2 is a view in front elevation of a window with the guard in open position;

Fig. 3 is a sectional view taken along line III-III of Fig. 2;

Fig. 4 is a sectional view drawn to a larger scale along line IVIV of Fig. 1;

of Fig. 4; and

Fig. 6 is a detail fragmentary view in side elevation of the guard removed from the window. 7

Referring now to the drawing, wherein like numerals refer to the same parts throughout, the preferred form of guard is applied to a window having a frame 10, an upper sash 11 and a lower sash 12. Arranged in the window frame are guide rails 13, 14 and 16 which cooperate toform spaced guides for the upper and lower sashes of thewindow, permitting their being raised or lowered. The lowor rail 17 of the upper sash 11 and the upper rail 18 of the lowersash 12 are provided with the usual cooperating beveled portions so that the'rail 18 overlaps the rail 17 when the window is closed.

, Secured to the guide rails 14 are a pair of vertically disposed, channel-shaped guide Fig. 5 is a sectional view along line VV Application members 19, providing opposed runways for the guard. The guides 19-areconveniently secured to the sash guide rails 14 by a'plura'lity of screws 20, which, as will be seen from the drawing, are covered so as to be inaccessible when the guard is closed. The sash rails '17 and 18 are notched, as shown at 21 and 22 endsfitting into the guide means 19 and adapted to move freely therein. As may be seen more clearly in Fig. ,6, the upperbar 26 V is provided with runners 31, the bar'27'with runners 32,'tl'1e bar 28 with runners 33'and the bar 29 with-runners 34.. These several runners are disposed in overlapping'relation, forming a telescopic arrangement which'permits the bars to-lie close together as shown in Fig. 2 when the guard is opened and collapsed. The runners 31'to 34 inclusive are provided at their upperends' with=horizonjtally extending, interengaging elements 86, 37, 38 and 39,'respectively. The lengths-of the respective runners 31 to 34m such that when the horizontally extending elements 36 to 39 are in engagement, the guard is closed and the bars are held in'pred'etermined spacedrelation. When in'the closed posit1on, downward movement of the-upper bar 26, and consequently-theother bars, is pr'e-I vented by engagement of the elements '36 with the'upper edges ofclosure members or cross walls 41 on the guide channels'l9.

' In order to lock the guard in its closed'position and with thebarsin their fixed spaced relation, I provide, on the upper element 39,

a pivoted latch or look 42 held in place by a screw 43 and adapted to'coac't with'a notch 44 provided in the upper sash 11 and a notch 45p'rovided in' the guide 19. As may be seen from Fig. 5, with the latch 42 in notch 45, the guard is securely held in closedposition and the latch isonly accessible from the inside of the window, and when the sash 12 is 1 lowered. If the latch is turned far enough to engage the notch 44 in the sash 11, the sash 11 is locked against lowering.

In the up er end of the guide means 19, on each side of the window, and at right angles to the notch 45, is provided anotch 46 which permits the latch 42 to be turned around to the dotted position shown in Fig. 5, in which osition it overhangs the upper rail 18 of the ower sash 12. With the latch 42in this position when the-lower sash 12 israised it raises the lower bar 29 which, in turn engages the bar 28, the bar 28 engages the bar 27 and so on, thus raising all of the-bars telescoping the runners 31 to 34 inclusive, and opening or collapsing the guard." When in raised position, the upper horizontally. extending elements 39 are engaged by a pair of spring catches 51 arranged in the sides of the window frame, so as to hold the, guard in its openposition. In this position, it is not unsightly," and does not give the appearand the guard may be locked, after lowering ance of a barred window. Whenever it is desired to close the guard to prevent intruders' from entering, the catches 51 are disengaged, the bars are lowered until the elements 36 engage the-closure member 41 and all of the horizontally extending elements are lying one on top of the other. The bars are" then in theirhproperly spaced relation,

the sash 12, by means of the latch 42. In this position, the lower sash 12 may be freely raised and put in any desired position, without interfering with the guard, and the upper sash 11 is firmly-locked in place with the guard. v

From the foregoing, it will be apparent that I have devised an improved collapsible window againstvintruders and may befopened to occupy very'little space when desired.' F urther, all'of the parts canbemanufactured at:

a; relatively low cost and will occupy a minimum shipping space. Moreover, any ordinary carpenter can secure the parts to a window.

Obviously, the present invention is not restricted to the particular embodimentthereof herein shown and described. Moreover, ,it is not indispensable that all the features of the invention be used conjointly, since they'may be employed advantageously in Various combinations and sub-combinations.
